✔ Best Answer
Here's a link to the motherboard info:

Your problem might be caused by a bad CMOS battery. Its job is to keep the BIOS settings in memory when the system is unplugged. If you had the BIOS custom configured & the battery died, the settings will return to the factory defaults. Is a video card installed or does the VGA cable connect to the motherboard output? If there's a card, temporarily remove it, connect the VGA cable to the board output, then power up & see if you get a display. If you do, immediately enter the BIOS & check the settings. If the date & time are wrong (like 10 years off), that's a fair indication the battery needs to be replaced. Most boards use a CR2032 battery. If you have a Dollar Tree near you, you can get them for a buck.
